Agilent Running ASTM Method D4815 for Determining Oxygenates in Gasoline on the Agilent 6820 GC Manual
User Manual
The document describes an analytical method for the determination of ethers and alcohols in gasolines using the Agilent 6820 gas chromatography system. This method utilizes a 10-port switch valve and two columns. The specific compounds determined include methyl tert-butylether (MTBE), ethyl tert-butylether (ETBE), tert-amylmethylether (TAME), diisopropylether (DIPE), methanol, ethanol, isopropanol, n-propanol, isobutanol, tert-butanol, sec-butanol, n-butanol, and tert-pentanol. 1,2-dimethoxyethane (DME) is used as the internal standard for quantitative analysis. The Agilent 6820 GC is used to run ASTM Method D4815 for determining oxygenates in gasoline.
